windows环境下搭建DB2 单物理节点 DPF 数据库

本文讲述了windows环境下，如何搭建一个单物理节点，4个逻辑节点的DPF数据库环境

1.) 安装DB2产品，假设安装信息如下：
DB2 副本名称：                           DB2COPY1
目标目录：                               C:\db2installpath                                     


新建实例：                              
    实例名：                             DB2
        重新引导时启动实例：             否
        TCP/IP 配置：                  
            服务名称：                   db2c_DB2
            端口号：                     50000
        实例用户信息：                  
            用户名：                     miaoqingsong


2.） 安装完成之后，会默认创建一个实例，实例名DB2，实例目录为C:\ProgramData\IBM\DB2\DB2COPY1\DB2， 在这个目录下，可以看到db2node.cfg文件


3.） 添加节点
C:\windows\system32>db2start DBPARTITIONNUM 1 ADD DBPARTITIONNUM HOSTNAME ADMINIB-PR7US3I PORT 1 COMPUTER ADMINIB-PR7US3I USER miaoqingsong PASSWORD yourpwd
2015-11-16 21:26:48     1   0   SQL1489I  The add database partition server  operation was successful. The new database partition server "1" is active.
SQL1489I  The add database partition server  operation was successful. The new database partition server "1" is active.


C:\windows\system32>db2start DBPARTITIONNUM 2 ADD DBPARTITIONNUM HOSTNAME ADMINIB-PR7US3I PORT 2 COMPUTER ADMINIB-PR7US3I USER miaoqingsong PASSWORD yourpwd
2015-11-16 21:27:15     2   0   SQL1489I  The add database partition server  operation was successful. The new database partition server "2" is active.
SQL1489I  The add database partition server  operation was successful. The new database partition server "2" is active.


C:\windows\system32>db2start DBPARTITIONNUM 3 ADD DBPARTITIONNUM HOSTNAME ADMINIB-PR7US3I PORT 3 COMPUTER ADMINIB-PR7US3I USER miaoqingsong PASSWORD yourpwd
2015-11-16 21:27:27     3   0   SQL1489I  The add database partition server  operation was successful. The new database partition server "3" is active.
SQL1489I  The add database partition server  operation was successful. The new database partition server "3" is active.




查看C:\Windows\System32\drivers\etc\services和hosts文件，可以看到如下内容
db2c_DB2 50000/tcp


db2icv101 51000/tcp
DB2_DB2   60000/tcp
DB2_DB2_1 60001/tcp
DB2_DB2_2 60002/tcp
DB2_DB2_3 60003/tcp
DB2_DB2_4 60004/tcp
DB2_DB2_END 60005/tcp


C:\ProgramData\IBM\DB2\DB2COPY1\DB2\db2nodes.cfg
0 ADMINIB-PR7US3I ADMINIB-PR7US3I 0
1 ADMINIB-PR7US3I ADMINIB-PR7US3I 1
2 ADMINIB-PR7US3I ADMINIB-PR7US3I 2
3 ADMINIB-PR7US3I ADMINIB-PR7US3I 3



C:\windows\system32>db2stop
2015-11-16 21:27:46     0   0   SQL1032N  No start database manager command was issued.
2015-11-16 21:27:47     1   0   SQL1064N  DB2STOP processing was successful.
2015-11-16 21:27:47     2   0   SQL1064N  DB2STOP processing was successful.
2015-11-16 21:27:47     3   0   SQL1064N  DB2STOP processing was successful.
SQL6033W  Stop command processing was attempted on "4" node(s).  "3" node(s) were successfully stopped.  "1" node(s) were already stopped.  "0" node(s) could not be stopped.



4.)启动实例，创建并连接到数据库
C:\windows\system32>db2start
2015-11-16 21:29:03     2   0   SQL1063N  DB2START processing was successful.
2015-11-16 21:29:03     3   0   SQL1063N  DB2START processing was successful.
2015-11-16 21:29:04     1   0   SQL1063N  DB2START processing was successful.
2015-11-16 21:29:06     0   0   SQL1063N  DB2START processing was successful.
SQL1063N  DB2START processing was successful.

报错与解释：

如果不是使用默认的实例DB2，您创建实例的时候需要指定 -s ESE -u username，之后才能创建多分区环境，否则会报错 SQL1096N  The command is not valid for this node type.

正确的方法如下：

C:\windows\system32>db2icrt dpf10 -s ESE -u miaoqingsong
Enter current password for miaoqingsong:
DB20000I  The DB2ICRT command completed successfully.


C:\windows\system32>db2ilist
DPF10
DB2INST1


C:\windows\system32>set db2instance=dpf10


C:\windows\system32>db2start DBPARTITIONNUM 1 ADD DBPARTITIONNUM HOSTNAME ....
